This lesson explores the different types of behaviors in animals, focusing on social behavior, territorial behavior, and communication. Students will learn about courtship and mating, caring for the young, claiming territories, and protecting each other. They will also explore different forms of communication, including chemical communication and sound communication. The lesson also covers cyclic behaviors such as hibernation and migration.

Social Behavior • Social Behavior – interactions among organisms of the same species. • Examples • Courtship and mating • Caring for the young • Claiming territories • Protecting each other • Getting food • A society is a group of animals of the same species living and working together in an organized way.

Territorial Behavior • A territory is an area that an animal defends from other members of the same species. • Territories contain food, shelter, and potential mates. This is MY tree!
Territorial Behavior • Defending territory from members of the same species is an instinctive behavior. • Aggression is a forceful behavior used to dominate or control another animal. • Submission – animals might show submissive behavior to avoid conflict, to avoid being injured, or to show that another animal is dominant.

Communication • Communicationis an action by the sender that influences the behavior of a receiver. • Courtship behavior is one type of communication that is performed before mating. • Chemical communication uses pheromones, which are chemicals produced by one animal that influence the behavior of another animal of the same species.

Communication • Sound communication is used by vertebrates and many insects. • Light communication • Certain kinds of flies, marine organisms, and beetles have a special form of communication called bioluminescence. • Bioluminescence may be used to lure prey, escape predators, or serve as marks of recognition.

Cyclic behavior is an innate behavior that occurs in a repeating pattern, often in response to changes in the environment. • Circadian rhythm – behavior based on a 24-hour cycle. • Animals that are active during the day are diurnal. • Animals that are active at night are nocturnal. Cyclic Behavior
Cyclic Behavior • Hibernation is a cyclic response to cold temperatures and limited food supplies. • An animal in hibernation remains inactive until the weather becomes warm in the spring. • Body response – body temperature and breathing rate drop. • Some mammals and many amphibians and reptiles hibernate.

Estivation • State of reduced activity similar to hibernation. • Desert animals sometimes estivate due to lack of food or periods of drought. • Migration is the instinctive seasonal movement of animals. • Many birds and mammals move to new locations when the seasons change. • Most animals that migrate do so in order to find food or to reproduce in an environment that is more favorable for the survival of its offspring.
